The main ladder 1 and the secondary ladder 2 are rotatably connected by the two hinges 3. Buffer rubber blocks are symmetrically fixed to the bottom of the front of the main ladder 1. The two U-shaped mounting plates 4 are located on the back of the secondary ladder 2. The lighting mechanism 5 is set on one side of the hinges 3 and is used for auxiliary lighting.

[0054] The lighting mechanism 5 includes an assembly hole, a T-shaped assembly ring 51, an annular groove, a rotating ring 52, a mounting base 53, a lighting lamp 54, multiple light-transmitting holes 55, multiple light-transmitting glass 56, a mounting base 57, a lighting lamp 58, multiple light-transmitting holes 59, a switch button 50, a U-shaped force-applying rod 510, a rectangular groove, a magnet 511, a series assembly, and a switch assembly. The assembly hole is located at the top of the main ladder 1. The outer wall of the T-shaped assembly ring 51 is threaded to the inner wall of the assembly hole. The T-shaped assembly ring 51, rotating counterclockwise within the assembly hole, will move vertically upwards. The annular groove is located at the top of the T-shaped assembly ring 51. The inner wall of the T-shaped assembly ring 51 is reinforced, and the rotating ring 52 is disposed in the inner cavity of the annular groove. The annular groove and the rotating ring 52 are used to prevent the mounting base 53 from rotating with the T-shaped assembly ring 51. The mounting base 53 is fixedly connected to the inner cavity of the rotating ring 52. The lighting lamp 54 is fixedly installed at the bottom of the mounting base 53. Multiple light-transmitting holes 1 are equidistantly opened on the outer wall of the main ladder 1. The multiple light-transmitting holes 1 are respectively located above each crossbar of the main ladder 1. Multiple light-transmitting glass 1 55 are fixedly connected to the inner cavity of the corresponding light-transmitting hole 1. The second mounting base 56 is fixedly inserted and connected to the bottom of the secondary ladder 2. The second lighting lamp 57 is fixedly installed on the second mounting base 2. At the top of mounting base 56, multiple light-transmitting holes 2 are equidistantly opened on the outer wall of secondary ladder 2. These holes 2 are located above each crossbar of secondary ladder 2. Multiple light-transmitting glass 2 58 are fixedly connected to the inner cavity of the corresponding light-transmitting holes 2. A switch button 59 is fixedly installed at the bottom of mounting base 2 56. The switch button 59 is used to control the switching of lighting lamp 2 57 and lighting lamp 1 54. A U-shaped force-applying rod 510 is fixedly connected to the top of T-shaped assembly ring 51. The U-shaped force-applying rod 510 facilitates the worker to apply force to rotate the T-shaped assembly ring 51 and move lighting lamp 1 54. The outer wall of the U-shaped force-applying rod 510 has... It has evenly distributed anti-slip textures, which are used to increase the friction between the U-shaped force bar 510 and the operator's palm. A rectangular groove is opened on the front of the U-shaped force bar 510. A magnet block 511 is fixedly connected to the inner cavity of the rectangular groove. The magnet block 511 can be attracted to the top of the fire truck, which improves the stability of the first lighting lamp 54 placed on the top of the fire truck. The series assembly is set on one side of the hinge 3. The series assembly is used to connect the first lighting lamp 54 and the second lighting lamp 57 in series.

Both fixing plates 513 are fixedly connected to the inner wall of the main ladder 1, and the guide wheel 514 is rotatably connected between the two fixing plates 513. The guide wheel 514 plays a guiding role.

[0056] The switch assembly includes a disassembly hole, two fixing blocks 515, a switch plate 516, a threaded hole, a through hole, and a switch bolt 517. The disassembly hole is located on one side of the secondary ladder 2, and its size should facilitate the disassembly and assembly of the lighting lamp 57 by the disassembly and assembly personnel. The two fixing blocks 515 are symmetrically fixedly connected to one side of the secondary ladder 2. The switch plate 516 is rotatably connected between the two fixing blocks 515. The threaded hole is located on one side of the secondary ladder 2, and the through hole is located on one side of the switch plate 516. The switch bolt 517 is movably sleeved in the inner cavity of the through hole. The outer wall of the switch bolt 517 is threadedly connected to the inner wall of the threaded hole. When the switch bolt 517 is rotated counterclockwise in the threaded hole, it will gradually disengage from the threaded hole.

[0057] Working principle of this utility model:

[0058] When firefighters need to operate the water cannon by climbing the rear ladder of the fire truck to the roof in a dimly lit or poorly lit environment, they can press the switch button 59 below the secondary ladder 2. At this time, the switch button 59 will turn on the second lighting lamp 57 and the first lighting lamp 54. The first lighting lamp 54 and the second lighting lamp 57, which are lit in the main ladder 1 and the secondary ladder 2 respectively, will illuminate each crossbar of the rear ladder of the fire truck through multiple light-transmitting holes 1 and 2 respectively. Then, the folded rear ladder of the fire truck can be opened and climbed to the roof of the fire truck. After climbing to the roof of the fire truck, the T-shaped assembly ring 51 is rotated counterclockwise in the assembly hole by the U-shaped force bar 510. When the T-shaped assembly ring 51 is completely disengaged from the assembly hole, the first lighting lamp 54 is placed on the roof of the fire truck by the U-shaped force bar 510 to provide auxiliary lighting and reduce the risk of firefighting operations.
